Function Documentation

add_glyph_texture()

void add_glyph_texture

(

s8

glyphIndex

)

Adds an individual glyph to be rendered.

char_to_glyph_index()

s8 char_to_glyph_index

(

char

c

)

Converts a char into the proper colorful glyph for the char.

clip_to_bounds()

void clip_to_bounds	(	s32 *	x,
		s32 *	y
	)

Clips textrect into the boundaries defined.

format_integer()

void format_integer	(	s32	n,
		s32	base,
		char *	dest,
		s32 *	totalLength,
		u8	width,
		s8	zeroPad
	)

Formats an integer n for print by fitting it to width, prefixing with a negative, and converting the base.

int_pow()

s32 int_pow	(	s32	n,
		s32	exponent
	)

Returns n to the exponent power, only for non-negative powers.

parse_width_field()

void parse_width_field	(	const char *	str,
		s32 *	srcIndex,
		u8 *	width,
		s8 *	zeroPad
	)

Determines the width of the number for printing, writing to 'width'.

Additionally, this determines if a number should be zero-padded, writing to 'zeroPad'.

print_text()

void print_text	(	s32	x,
		s32	y,
		const char *	str
	)

Prints text in the colorful lettering at given X, Y coordinates.

print_text_centered()

void print_text_centered	(	s32	x,
		s32	y,
		const char *	str
	)

Prints text in the colorful lettering centered at given X, Y coordinates.

print_text_fmt_int()

void print_text_fmt_int	(	s32	x,
		s32	y,
		const char *	str,
		s32	n
	)

Takes a number, finds the intended base, formats the number, and prints it at the given X & Y coordinates.

Warning: this fails on too large numbers, because format_integer has bugs related to overflow. For romhacks, prefer sprintf + print_text.

render_text_labels()

void render_text_labels

(

void

)

Renders the text in sTextLabels on screen at the proper locations by iterating a for loop.

render_textrect()

void render_textrect	(	s32	x,
		s32	y,
		s32	pos
	)

Renders the glyph that's set at the given position.

Variable Documentation

sTextLabels

struct TextLabel* sTextLabels[52]

Stores the text to be rendered on screen and how they are to be rendered.

sTextLabelsCount

s16 sTextLabelsCount = 0
